（重定向自Technical rate of substitution）

In microeconomic theory, the Marginal Rate of Technical Substitution (MRTS)—or Technical Rate of Substitution (TRS)—is the amount by which the quantity of one input has to be reduced ( $-\Delta x_2$ ) when one extra unit of another input is used ( $\Delta x_1 = 1$ ), so that output remains constant ( $y = \bar{y}$ ).
